Featuring a precise 5:1 resin-to-hardener ratio with color-coded pumps, it offers fast or slow curing options tailored to your environment. Its self-leveling formula ensures smooth fiberglass wetting and durable, waterproof repairs resistant to chemicals, abrasion, and weather—perfect for boat building, composite construction, and professional-grade restoration projects. ## Description TotalBoat Traditional 5:1 epoxy resin is a versatile marine grade system with greater tensile strength and durability in harsh environments compared to polyester resin. Use marine epoxy to bond, plaster, net, fair or laminate - few epoxy systems offer this level of versatility when it comes to fiberglass boat construction and repair, industrial composite construction or carpentry projects. Working with fiberglass? Its low viscosity and self-leveling properties make TotalBoat 5:1 resin ideal for wetting fiberglass, laminating, wood penetration, gelcoat bulb repair, weather and waterproofing, and other marine applications. Use TotalBoat 2-piece epoxy resin kits to build, repair and repair boats and boats including canoes, kayaks, paddle boards or surfboards. It is also suitable for carpentry, RV delamination repairs, auto repairs and all kinds of composite manufacturing. Mix this fiberglass epoxy resin with fillers and thickeners like microballoons, wood flour and silica to create threading compounds, fairing compounds, and high-strength bonding adhesives. Compatible with concrete, stone, most metals, wood and reinforcing fabrics including glass fiber and carbon fiber. Hardened epoxy can be sanded, shaped and painted. The hardened resin is resistant to abrasion, shock, scratches, solvents, salt and is 100% waterproof. Choose quarter, gallon and 4.5 gallon epoxy kits with your choice of slow or fast hardener. Slow hardener extends working and hardening time in warmer conditions. Choose a fast hardener at colder temperatures or when maximum curing speed is desired. Each kit includes resin, hardener and color-coded calibrated pumps. It's as simple as a resin pump for 1 hardener pump for an accurate 5:1 ratio and perfect hardening. Apply epoxy with brush, roller, syringe or spreader. Compare TotalBoat 5:1 Marine Epoxy Resin to West System 105 Epoxy Resin with 205 or 206 Hardener, MAS Epoxy, System 3 Epoxy and other Marine Fiberglass Repair Kits. Review: Cures very hard. - Best epoxy for carbon fiber. We are asking seriously stong structural material with this. Review: Great product. Superior strength over poly based resin. - Great product. Learned about epoxy based resin and polyester resin on Youtube. Glad I found that info and I purchased Total Boat Epoxy to repair two snowmobiles. Both hoods one a simple crack and the other pretty much a big mess with multiple cracks and problems including a body with a torn out front hinge. On that I glassed in a couple layers of woven glass on the inside of a messy fiberglass tear after trimming it up a little. It's a vintage 70's sled with a fiberglass body. Duct tape was used as a soft form on the outside and it looks just great. Nearly zero transition between the epoxy and existing gelcoat. The repair feels as strong as the original if not slightly stiffer than the other side. I have yet to run it and see if the repair will hold. My prep work was very careful. Degreasing and lightly air sanding with a 2 inch 3M disc to expose fresh material to adhere to. Masking tape makes great dams and protects surrounding hardware I found. I am confident these repairs will last and I don't think I could say that if I were using a polyester based resin. I did pop the left over cured resin out of the mix cup and tried to break it. I could on the thinner cured part, but it was clear it was a pretty strong material. I ordered the fast cure and in a heated shop at 70 degrees it took a long time to cure I thought. Just about two hours. And I am reading that that is normal at that temp. I am however very used to automotive products cure times which is much quicker as in minutes. No hurry with this stuff unless it's very warm out. Wear your PPE as this stuff has a strong odor till it cures. And it sticks to everything. Gloves and disposable brushes are a must. Overall the product was great to work with. I see many other applications for this product. I have only used fiberglass products a couple times before. So an amateur I am. Good stuff. Great strength. Easy to work with. I measured and did not use the dispensers. So I cannot comment on those. 5 stars ## Features - High Strength Marine Epoxy Resin Kits: System formulated for bonding, coating and laminating.

It is epoxy with a 5 to 1 ratio, and cures extremely hard. Polyester should not be used on a repair below the water line. Epoxy will not allow water to absorb into the repaired area. **Q: can I use this to fix lamination on my RV side walls** A: Worked great for me rebuilding the wall sandwich (fiberglass, thin ply, foam board,,,) after water delamination. **Q: Can you do inside of bathtub with this?** A: Good Afternoon, this product cures to a high strength, water resistant finish, so using within a bathtub should be fine. Thank you. ## Customer Reviews ### ⭐⭐⭐⭐ Cures very hard. *by M***. on 30 November 2020* Best epoxy for carbon fiber.
